Description
Technical Field
[0001] The utility model belongs to the technical field of assembly tools and relates to an assembly tool for automobile radiators, in particular to a flaring knife for assembling B-type radiating pipes. Background Art
[0002] An automotive radiator is an essential component in a car engine's cooling system. It dissipates excess heat from the coolant in the engine's water jacket into the atmosphere through heat exchange, driven by forced airflow. The radiator core typically consists of heat pipes, heat strips, and a frame. Designed to suit the application, the radiator's shape and structure vary. Air flows through the ducts formed by the parallel heat pipes and heat strips, cooling the coolant within them.
[0003] Heat pipes are typically made from high-frequency welded, flat, hollow aluminum tubes. B-type heat pipes are a common type of pipe used in the automotive radiator industry. During radiator core assembly, the thin tube walls of the heat pipes can easily deform under pressure, requiring adjustment of the installation position. Existing heat pipe assembly requires inserting both ends of the pipe into the motherboard. This is typically done by assemblers using simple metal plates or clamps inserted into the tube openings for correction and adjustment. This is inconvenient and impacts production efficiency. This is especially true for B-type heat pipes, which lack dedicated adjustment tools, making the process time-consuming and labor-intensive.
[0004] Therefore, a flaring knife for assembling a B-type radiating pipe is designed to facilitate adjustment and pipe opening correction when the B-type radiating pipe is installed. Utility Model Content
[0005] The purpose of the utility model is to address the above-mentioned problems in the existing technology and propose a flaring knife for assembling B-type radiator pipes. The technical problem to be solved by the device is: how to improve the convenience of correction and adjustment during the assembly of B-type radiator pipes, facilitate the operation of assemblers, and improve assembly efficiency.
[0006] The purpose of this utility model can be achieved through the following technical solutions:
[0007] A flaring knife for assembling a B-type heat pipe comprises a knife handle for hand-holding and a knife head for inserting into the B-type heat pipe for adjustment. The knife head is arranged at one end of the knife handle. The structure of the knife head is designed to match the inner hole structure of the B-type heat pipe. A partition is provided in the middle of the B-type heat pipe. An avoidance groove matching the partition is provided on the knife head. When the knife head is inserted into the B-type heat pipe, the partition is inserted into the avoidance groove. The knife head comprises a transition section and an adjustment section. The transition section is located in front of the adjustment section. The thickness of the transition section is thinner than that of the adjustment section, and the thickness of the adjustment section gradually increases from front to back. Arc transitions are provided on both sides of the front end of the knife head.
[0008] With the above structure, the gradually thickened cutter head structure facilitates the insertion and removal of the cutter head and can prevent the cutter head from getting stuck in the B-type heat pipe.
[0009] When assembling the radiator core, the B-type heat pipe is inserted into the mounting mainboard. The assembler holds the flaring knife, inserts the knife head into the B-type heat pipe, and adjusts the position of the B-type heat pipe. At the same time, the deformed pipe mouth can be corrected by shaking the flaring knife. The operation is simple and convenient.
[0010] The handle and blade are made of stainless steel. Stainless steel flaring knives are low in cost, high in strength, rust-proof, durable and have a long service life.
[0011] The front end of the avoidance groove is provided with an opening groove, which is V-shaped. The width of the avoidance groove is greater than the thickness of the partition. The V-shaped opening groove facilitates the introduction of the partition into the avoidance groove, thereby facilitating the insertion of the cutter head.
[0012] The width of the cutter head is smaller than the inner hole width of the B-type heat dissipation pipe, and the two are matched with each other with a clearance, which is convenient for inserting and removing the cutter head. On the other hand, when correcting the deformed pipe mouth, the cutter head has a certain movable margin, which is convenient for adjustment.
[0013] The front end of the cutter head is provided with a slope, and the slope is located in the front part of the transition section.
[0014] With the above structure, a slope is provided to make the front end of the cutter head thinner, so that the cutter head is easy to insert into the pipe opening of the B-type heat dissipation pipe.
[0015] A rib is provided at the connection between the cutter head and the cutter handle, and the width of the rib is greater than the width of the inner hole of the B-type heat dissipation pipe.
[0016] With the above structure, after the cutter head is inserted into the B-type heat pipe, the rib can block the pipe mouth to prevent the cutter handle from being inserted into the B-type heat pipe for limiting the position. The flaring cutter is not easy to loosen, which is convenient for adjusting and correcting the B-type heat pipe.
[0017] The edges and corners of the knife head and the knife handle are ground to prevent scratches on staff.
[0018] The handle is provided with an anti-slip cover to facilitate hand-held operation by staff.
[0019] Compared with the existing technology, this B-type radiator pipe assembly flaring knife has the following advantages:
[0020] 1. This flaring knife is designed to match the structure of the B-type heat pipe. When assembling the radiator core, after the B-type heat pipe is inserted into the mounting hole of the mounting motherboard, the assembler inserts the knife head into the B-type heat pipe, and the partition in the middle of the B-type heat pipe is inserted into the avoidance groove. The assembler can adjust the position and angle of the B-type heat pipe on the mounting motherboard by holding the knife handle, which is relatively convenient to operate.
[0021] 2. This flaring knife can correct the deformed pipe mouth. After inserting the cutter head, apply force to pry the pipe mouth to correct the deformed part of the pipe mouth. The operation is simple and convenient.
[0022] 3. The flaring knife has a simple structure, low production cost, and is easy to use, and can improve the assembly efficiency of the B-type heat pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] See also Figure 1-6 The present embodiment provides a flaring knife for assembling a B-type heat pipe, comprising a handle 1 for hand-holding and a blade 2 for inserting into a B-type heat pipe 3 for adjustment. The blade 2 is arranged at one end of the handle 1. The structure of the blade 2 is designed to match the inner hole structure of the B-type heat pipe 3. A partition 31 is provided in the middle of the B-type heat pipe 3. The blade 2 is provided with an avoidance groove 21 that matches the partition 31. When the blade 2 is inserted into the B-type heat pipe 3, the partition 31 is inserted into the avoidance groove 21. The blade 2 includes a transition section 26 and an adjustment section 27. The transition section 26 is located at the adjustment section 27. At the front, the thickness of the transition section 26 is thinner than the adjustment section 27, and the thickness of the adjustment section 27 gradually increases from front to back. Arc transitions 23 are provided on both sides of the front end of the cutter head 2. The gradually thickening cutter head structure facilitates the insertion and removal of the cutter head 2, and can prevent the cutter head 2 from being stuck in the B-type heat pipe 3. When the radiator core is assembled, the B-type heat pipe 3 is inserted into the mounting mainboard 4. The assembler holds the flaring knife, inserts the cutter head into the B-type heat pipe 3, and adjusts the position of the B-type heat pipe 3. At the same time, the deformed pipe mouth can be corrected by shaking the flaring knife, and the operation is simple and convenient.
[0035] Preferably, in this embodiment, the knife handle 1 and the knife head 2 are made of stainless steel plates, which have low production costs, high strength, no rust, good durability and long service life.
[0036] An opening groove 22 is provided at the front end of the avoidance groove 21. The opening groove 22 is V-shaped. The width of the avoidance groove 21 is greater than the thickness of the partition 31. The V-shaped opening groove 22 facilitates the introduction of the partition 31 into the avoidance groove 21, thereby facilitating the insertion of the cutter head 2.
[0037] The width of the cutter head 2 is smaller than the inner hole width of the B-type heat dissipation tube 3, and the difference is 2%-4% of the inner hole width of the B-type heat dissipation tube 3. The two are clearance-matched, which facilitates the insertion and removal of the cutter head on the one hand, and on the other hand, when correcting the deformed pipe mouth, the cutter head 2 has a certain movable margin, which is convenient for adjustment.
[0038] The front end of the cutter head 2 is provided with a slope 25 , which is located in front of the transition section 26 . The slope 25 makes the front end of the cutter head thinner, making it easier for the cutter head 2 to be inserted into the pipe opening of the B-type heat dissipation pipe 3 .
[0039] A rib 24 is provided at the connection between the cutter head 2 and the handle 1. The width of the rib 24 is greater than the width of the inner hole of the B-type heat dissipation tube 3. After the cutter head 2 is inserted into the B-type heat dissipation tube 3, the rib 24 can block the tube mouth to prevent the cutter handle 1 from being inserted into the B-type heat dissipation tube 3 and limit it. The flaring knife is not easy to loosen, which facilitates adjustment and correction of the B-type heat dissipation tube 3.
[0040] The edges and corners of the blade head 2 and the handle 1 are ground to prevent scratches on the staff.
[0041] The handle 1 is provided with an anti-slip cover to facilitate hand-held operation by staff.
[0042] The working principle of this utility model:
[0043] The utility model provides a flaring knife for assembling a B-type heat pipe. The flaring knife is designed according to the structure of the B-type heat pipe 3. When the radiator core is assembled, the B-type heat pipe 3 is inserted into the mounting mainboard 4. The end of the B-type heat pipe 3 needs to extend out of the mounting mainboard 4. The heat pipe needs to be adjusted to adjust the insertion distance of the heat pipe and keep it perpendicular to the mounting mainboard 4. The flaring knife for assembling a B-type heat pipe is simple and convenient to adjust, and has high efficiency. After the B-type heat pipe 3 is inserted into the mounting hole of the mounting mainboard 4, the assembler inserts the cutter head 2 into the B-type heat pipe 3, and the partition 31 in the middle of the B-type heat pipe 3 is inserted into the avoidance groove 21. Since the cutter head 2 gradually thickens, the B-type heat pipe 3 can be clamped with appropriate force. The assembler can adjust the position and angle of the B-type heat pipe 3 on the mounting mainboard 4 by holding the knife handle 1, and the operation is relatively convenient. If the nozzle of the B-type heat pipe 3 is deformed, after inserting the cutter head 2, the nozzle can be pried with force to correct the deformed part of the nozzle.
[0044] The above describes in detail the preferred embodiments of this patent, but this patent is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of this patent.
